Title: Manufacture of welded tube excellent in roundness
Inventor: NAKAKO TAKEFUMI
IPC: B21D3/14
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain the welded tube of product having high roundness in all of the tip, rear end and the middle. SOLUTION: After bending a metallic strip 2 in the width direction and executing butt welding 7 of both end parts in the width direction in a state where the cross section is held in an approximately round shape, the welded tube stock 8 is flatly worked with over-bend rolls 9 so that the distance from the weld zone to the tube-bottom part becomes smaller than the targeted outside diameter of product and, next, the welded tube stock is formed into an approximately round shape with straightening rolls 11. In flattening work, it is preferable to flatten the welded tube stock so that the distance from the weld zone to the tube-bottom part is 3-10% smaller than the targeted outside diameter of product.  When the out-of-roundness in the middle part of the tube is degraded by the flattening work, the rolling reduction with the straightening rolls 11 is adjusted in accordance with the amount of flattening with the over-bend rolls 9. Then, because residual stress is removed by the flattening work and straightening, the roundness of the welded tube of product which is obtained by cutting the welded tube stock 8 into standard length is not degraded even at the tube ends.

Title: Asphalt sheet for vibration damping of vehicle
Inventor: OGINO SUKEYUKI
IPC: B60R13/08
Filed: 1988-03-16
Abstract: PURPOSE:To provide a nonpollutive lightweight sheet of excellent vibration damping performance, by adding mica of a specified mesh as a vibration- damping material to an asphalt material as a base, kneading the mixture with other fillers and molding the resulting mixture into a sheet. CONSTITUTION:An asphalt material is used as a base, and mica of about 20 mesh is added as a vibration-damping material to this base. The obtained mixture is kneaded with other necessary fillers (e.g., waste paper or talc), and the resulting mixture is molded to produce an asphalt sheet for vibration damping. Unlike asbestos, the mica has no fear of causing pollution, and it is bulky and lightweight because of its size of about 20 mesh, can absorb in good efficiency a vibrational energy as in internal loss as a result of friction generated by vibration in the other materials and the voids, and can exhibit sufficient vibration damping performance.

Title: Small-sized zoom lens
Inventor: FUJIOKA IWATATSU
IPC: G02B15/20
Filed: 1985-03-27
Abstract: PURPOSE:To obtain excellent aberrations regardless of extremely small size and the small number of lens elements by composing the front group of the 1st group with negative refracting power, displacing the principal point of a rear group to an image side and dividing the rear group into the 2nd group with positive refracting power and the 3rd group with positive refracting power and moving the 2nd and the 3rd groups on the optical axis by different extents. CONSTITUTION:Inequalities 1-5 are hold. Inequality 1 is concerned in the range of the focal length of the 1st group for reducing the size of a zoom lens and improving its aberrations. Inequalities 2 and 3 uniform the quantity of peripheral light within the entire range from short focal length to long focal length by allowing the 3rd lens having positive refracting power to move during zooming by a proper movement extent less than the movement extent of the 2nd group with a proper range and a small-sized zoom lens which has an excellent coma aberration are obtd. Inequality 2 is for the reduction of a distortion aberration due to power variation in cooperation with inequality 4. When the 3rd group is constituted within the range of the inequality 4, sufficient aberrations including a chromatic aberration are obtained even with a single lens.
